Question

d. \as he moved down, he joined other water drops to form groundwater.\

1. when wally and other drops cool down in the atmosphere, what process happens?

a. runoff
b. infiltration
c. evaporation
d. condensation

1. why do the clouds become heavy and darker in the story?

a. because the water drops evaporate
b. because the clouds move toward the ocean
c. because they become too full of water
d. because wally finds an aquifer

Explanation:

Question 3

To solve this, we analyze each option:

• Runoff: Water flowing over land, not related to cooling in atmosphere. Eliminate A.
• Infiltration: Water entering soil, not about cooling in air. Eliminate B.
• Evaporation: Liquid to gas (heating), opposite of cooling. Eliminate C.
• Condensation: Gas (water vapor) to liquid (droplets) when cooling in atmosphere (forms clouds). This matches the scenario of cooling in the atmosphere.

Analyze each option:

• Option A: Evaporation turns liquid to gas (water drops would decrease, not make clouds heavy). Eliminate A.
• Option B: Cloud movement to ocean doesn’t make them heavy/darker. Eliminate B.
• Option C: Clouds become heavy and darker when they accumulate (condense) too much water (liquid droplets), making them full of water. This makes sense.
• Option D: Wally finding an aquifer (underground water) doesn’t affect cloud appearance. Eliminate D.

Answer:

D. Condensation
